nearly straight, finger and unguis not reaching apex of lobe (cf. T. 
novae-hollandiae Stebb.), numerous scattered spines on the joints; in 
2? 6th joint simple, shorter than 5th, both spinose, but without any 
specially large spines. 
Second gnathopod in &, 2nd joint very similar to that of T. australis 
but oval, greatest width just before the middle, whence tapering to 
hinge, palm and hind margin forming an almost even curve without 
defining tooth or process, palm convex, spinose, finger strongly curved, 
a little longer than palm and overlapping the margin atthe end; in ? 
2nd joint expanded on front margin, twice as long as wide, 4th not lobed, 
5th not very strongly lobed, 6th a little shorter than 5th, apical 
projection bluntly rounded. 
Second peraeopod, 7th joint with inner margin sinuous, not 
constricted. 
Third to fifth peraeopods, 2nd joint moderately expanded, its hind 
margin in 3rd and 4th peraeopods with minute setuliferous serrations, 
in 5th regularly crenulate and setulose. 
First uropod, outer ramus with apical spines only. 
Length: $ 12°5mm., 2? 10 mm. 
Colour: Whitish, eyes dark brown. 
Locality: West and East coasts of the Cape Peninsula. (Dr. W. F.

This species possesses a Ist gnathopod in ¢ like that of T. novae- 
hollandie Stebb. together with a 2nd gnathopod similar to that of 
T. brito Stebb. It is distinguished from T. australis by the greater 
proximity of the eyes, the 2nd side-plate, the 2nd gnathopod in ¢ and 
the finger of 2nd peraeopod. The females of this species and australis 
can be distinguished by the 2nd side-plate, the 2nd joint of 2nd 
enathopod and absence of large spines on 5th and 6th joints of Ist 
enathopod. 
The name is compounded of ayxs near, and esos an appearance.

In his generic diagnosis Methuen says: ‘‘ Like Talitrus except for the 
fifth side-plate. . . .” This refers presumably to the difference in the 
size of the lobes, the anterior lobe being much bigger than the posterior 
in Talitriator, but only a little bigger in Talitrus (cf. Sars’ figure of 
T. locusta in Crust. Norw. vol. 1, pl. 9).
